LED DECORATIVE LAMP
The LED decorative lamp contains a three-terminal LED device, a flexible core for the plugging of the three-terminal LED device, and a seat for the configuration of the flexible core. The seat contains three terminal plates for the electrical contact with the three terminals of the LED device. A lamp string formed by connecting multiple such LED decorative lamps enjoys accurate flash timing, thereby achieving appealing lighting effect.
The present invention generally relates to LED decorative lamps, and more particularly to a LED decorative lamp using three-terminal LED devices and a local passive IC to achieve accurate flash timing when multiple LED decorative lamps are connected into a lengthy lamp string.
(b) DESCRIPTION OF THE PRIOR ARTThe LED decorative lamp of the present invention refers to one that could be connected into a lamp string for the decoration of; for example, Christmas trees. As shown in
